原始问题使事情变得复杂，实际上问题要简单得多。
我尝试简单地运行现有的单元测试而不添加任何东西。在我运行的单元测试inet/tests/unit文件夹中：
./runtest
得到这个：

发生了什么事？
注意您可以避免实际阅读原始问题。除非你对某些人在这个问题上获得更多信息感到好奇。
我正在尝试在INet Framework中运行自定义测试，我正在为我正在编写的组件添加自定义测试。这些文件是this commit的一部分。
我在inet/tests/unit中添加了一个测试，请参阅文件结构的提交。

我不明白我做错了什么......甚至在这里发生了什么......
答案 0 :(得分：1)
从OMNeT ++ 4.2开始<platdep/sockets.h>必须在更改日志中提及<omnetpp.h>之前：
在inet中，他们通过在以下提交中调整src/makefrag来确保正确的顺序：
https://github.com/inet-framework/inet/commit/d9abbd1b4df5b9efcfb7a7f58e8f2223f4a91a33
因此，您必须使用以下代码在与makefrag相同的文件夹中添加Makefile文件：
PRECOMPILED_HEADER=<path-to-inet>/src/inet/common/precompiled.h
CFLAGS += -include $(PRECOMPILED_HEADER)
考虑用您的路径替换<path-to-inet>，例如../../
更新： OMNeT ++ 5.1预览3强调的更改日志，问题已解决：
Ordering of 'platdep/sockets.h' and 'omnetpp.h' is no longer important. It is recommended to include 'omnetpp.h' first.
